Thread Necromancy!
i was bored, and since I've been researching some Office alternatives, I thought I'd update this thread.
To replace Microsoft Office at work, I think we'll be paying $50 for ThinkFree Office and $69 for Nisus Writer Express. Now ThinkFree had a Word program, but all our Word-formatted docs didn't open well with it. They worked perfectly in Nisus, and Nisus is a faster, better-looking program. However, ThinkFree's Excel program, called Calc, is FANTASTIC! The best Excel alternative out there, IMO. ThinkFree also has Show, a PowerPoint-type program, but it's not great. The advantage with TF, though, is that it works with the Office formats, rather than using its own. Nisus, however, opens and saves in Word format.
So there you have it.
Edit: I've also recently discovered the joy of GraphicConverter.
